Abstract
A process for making inflatable tires Puncture Proof. wherein air filled spheres or bubbles (2) are coated with a quick drying glue (10) before being inserted into a mounted, deflated tire, which is then inflated and rotated at high speed to create the centrifugal force needed to disperse spheres (2) evenly while the glue (10) dries and also to balance the wheel (8) without the use of weights.
Claims
exact text as granted — not AI-modifiedI claim:
1. Apparatus for repairing a pneumatic tire comprising a container, a plurality of small flexible elements in said container, and means for injecting said plurality of small, flexible elements filled with gas into a said pneumatic tire.
2. Apparatus according to claim 1 wherein container further comprises uncured glue capable of curing when exposed to air in a said tire.
3. Apparatus according to claim 2 wherein each of said flexible elements comprises a thin rubber shell filled with gas.
4. Apparatus according to claim 3 wherein each of said small flexible elements is spherical and has a diameter of about 6 mm.Join the waitlist — get patent alerts
